the obama administration, president obama, during the campaign, has been open about his desire to try to engage iran bilaterally, a last ditch effort of diplomacy before resorting to other options. would a bilateral negotiation, were that to come about, give the u.s. an opportunity to engage on human rights issues? i mean, the u.s.' general policy is they want to keep it limited to arms control, but is that proper, or is there an opportunity or a window for the u.s. to engage with iran? >> there's always been a con accept issue -- there is a group of -- one point of view success that the agenda should be kept narrow because otherwise it gives the iranians the opportunity to diverse, talk about afghanistan, bahrain, syria, talk about this, that, and so the agenda has to be narrow as a need of focusing on the issue of the principle concern. that's one. that's con accept issue, as far as i can tell was never resolved. when an issue remains unresolved, the status quo revails. i suspect, given the fact the issue of a bilateral conversation is a last ditch effort, likely to remain focused.
